IMPROVED WATER-WHEEL.

use the same, reference being had to the accompanyingdrawings, forming part of this specification.

This invention relates to a new and improved water- Wheel, which is also applicable for measuring water, or may be used as a water-meter; and

It consists in the combination of the top plate having acurved Water-passage or channel in line with the supply-pipe, with the pivoted buckets, the annular groove in the bottoni of the case, the abutment within the groove, and the induction and eduction-pipes, as will be hereinafter more fully described.

In the accompanying sheet of drawings- Figure 1 is a plan or top view of my invention with the top plate removed.

Figure 2, a vertical section ofthe same, taken in the line x a', iig. 1.

Similar letters of reference indicate corresponding parts.

A represents a cylindrical box or case, inwhich the Wheel B is fitted, and allowed to turn freely.

C is the water-induction, and

D, the water-eduction pipe, the pipe C, (induction,) entering or communicating lwith A in a higher plane (See fig. 2.)

The wheel B is composed of a ring, c, anda hub, l1, between which the buckets c are suspended on pivots d, the bearings of the inner pivots being in slots in the upper surface of the hub b, and the bearings of the outer pivots being in the ring a.

The buckets are all pendent, and swing freely on their pivots, and when down 'rest against bearings l) outhe hub, which bearings are slightly inclined from a vertical plane, as shown clearly in 2.

The ring a rests upon a shoulder, c', in the case A.

The lower parts or edges of the buckets are rounded, and they are tted and work in an annular groove,tl in the case A, the buckets iitting in the groore as snugly as may be without creating undue friction.

The groove (ZX is not of the same dimensions entirely around the case, but has a ledge, e, inclined at oneend within it, between the induction and eduction-pipes C D.. l

This ledge is for the purpose of raising the buckets to a horizontal plane between the aforesaid pipes, so as to admit of tl ic revolution of the wheel, and to form an abutment'or cut-oli" between the pipes, so as to cause the water to tlow and act against the buckets, in the direction indicated by the arrows.

The water iinpinges against the buckets about ai right angles, and the wheel is properly enclosed within the case by a cap-plate, E, which is let into the top of the case, and held therein by the screw-cap plate 'E'.

By this arrangement it will be seen that the water l'lows through the case in one direction only, and is made to act in the most eil'jcient manner against the buckets of the wheel, a free discharge being allowed through the pipe D, the spacebetween the top of the abutment c and the under surface `oi' the top plate E, being just .suilicient to allow the buckets c to pass through when edgewise or in a horizontal position.

The top plate E is provided upon one side with a tangential passage or water-guide iu continuation of the supply-pipe C. This passage is curved downward from the periphery of the'plate to its under side, in such a manner that the water entering from the pipel C, is direc-ted and falls against the buckets at nearly a right angle.

The entering stream of water from O settles the buckets immediately as they leave the abutment c.

It will be seen from the above description that the device is applicable either a motor or meter; the revolutions ofthe wheel, when the. device is used as a meter, being registered in order to ascertain the amount of water discharged.

I claim as new, and Patent- The top plate E, with its channel or passage, in com binatin with the suspended or pivoted pendent buckets c of the wheel B, the groove l in the case A, the abutment c, within said groove, aud the induction and eduction-pipes C D, all arranged to operate in the manuell substantially as and for the purpose set forth.
